Distribution and Habitat

Allobates brunneus is found in a number of South American countries. Populations inhabit Brazil, Bolivia (the northern tip), French Guiana (though this may refer to another species), Guyana, Suriname, and Venezuela (south of the Orinoco River only). Within the Brazilian state of Mato Grosso, this species is found in lowland swamp forests areas along the banks of the slow-running Rio Casca and its tributaries, at 300-380 meters asl (Lima et al. 2009).
